I'm thinking now it is 'SMTP-WAKEUP' since we did make a server modification for retrieving mail from a backup server.

Yes, correct. It's also possible to see sessions tagged SMTPR - these are "reverse" SMTP sessions: the server initiates an outgoing SMTP session but then issues the ATRN command to reverse the mail flow.

I was just looking at the logs for tracking a message, and I have come across something I have not seen before. An SMTP session tagged with the following ID:
SMTPW-######

I have seen SMTPI-###### (for incoming I assume) and simply SMTP-######, but never an SMTPW-######.

Can anyone explain what the difference is with that one?[]
